eli5, If electricity is moving electrons, does the generator get them back?

806 views

So a generator is magnets and copper coil yeah? They make electricity and electricity is moving electrons. Power generators and electric stations are kilometres away. Do the copper coils get their electrons back?
Won’t the copper coil run out of electrons. How the electrons come back (if they do)?

No, electrons don’t fly all the way from the powerplant to your home and back whenever you turn on a lamp. It’s more like Newton’s cradle toy – powerplant gives it a whack from one end, the ball on the other end moves and that’s your light, but then balls settle as they were.
